Intel Vision Driver

This repository supports Intel Vision Driver on Intel Lunar Lake (LNL) CVS-enabled Platforms

Dependencies

• Intel LNL platform BIOS and CVS device
• Linux kernel v6.7-rc8 or later
• Intel LJCA USB driver, adding LNL GPIO PID (INTC10B5) support

Build instructions

Ways to build the USBIO drivers

1. build out of kernel source tree
2. build with dkms
3. build with kernel source tree aren't supported yet

Build was tested on Ubuntu 22.04 LNL CVS platform running kernel v6.7-rc8

Build out of kernel source tree

• Prerequisite: 6.7-rc8 (or later) kernel with ljca and gpio_ljca module/driver loaded, header and build packages, to install required package

$ sudo apt-get install build-essential

To compile the Intel Vision driver:

$ cd vision-drivers
$ make

Check LJCA drivers are loaded before vision driver can be installed

$ lsmod | grep -e ljca -e gpio_ljca     

Installing the vision driver

$ sudo insmod intel_cvs.ko 

Uninstall the vision driver

$ sudo rmmod intel_cvs

Build with dkms

a dkms.conf file is also provided as an example for building with dkms which can be used by dkms add, build and install.
